CVE-2026-98378

The Linux kernel contains a vulnerability in the bpf subsystem where the link iterator fails to skip unsettled links. Specifically, bpf_link_prime() inserts a link into link_idr before bpf_link_settle() publishes its ID. While bpf_link_by_id() correctly treats ID-zero links as unsettled, the link...

kernel: bpf: Fix use-after-free in bpf_uprobe_multi_link_attach()

A flaw was found in the Linux kernel's extended Berkeley Packet Filter eBPF subsystem. A privileged local attacker, with CAPSYSADMIN capabilities or root access, could exploit a use-after-free vulnerability in the bpfuprobemultilinkattach function. This issue arises when bpflinkprime fails, leadi...

CVE-2024-47675 bpf: Fix use-after-free in bpf_uprobe_multi_link_attach()

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix use-after-free in bpfuprobemultilinkattach If bpflinkprime fails, bpfuprobemultilinkattach goes to the errorfree label and frees the array of bpfuprobe's without calling bpfuprobeunregister. This leaks bpfuprobe-uprobe a...
